Blueberry plant named ‘ZZ04120’

ABSTRACT

A new and distinct northern high bush blueberry variety, ‘ZZ04120’ is described. The variety results from selection among a population of seedlings derived from the controlled crossing of the blueberry varieties ‘O&#39;Neal’ (seed parent) (not patented) and ‘Duke’ (pollen parent) (not patented). The fruit of this new variety has large, medium blue, attractive fruit which ripens in mid-season. The new variety appears suitable for the fresh fruit market.

Genus and species plant claimed: Vaccinium corymbosum.

Variety denomination: ‘ZZ04120’.

BACKGROUND OF THE INVENTION

The new variety of red raspberry, Vaccinium corymbosum, resulted fromselection among a population of seedlings derived from a controlledcross carried out in 2004 between ‘Brigitta’ (seed parent) (notpatented) and B7-8-1 (pollen parent) (not patented) located at Ruakura,Hamilton, New Zealand. ‘ZZ04120’ was identified in 2006 as havingpotential as a new variety due to its attractive, large, medium bluefruit with good flavour. It was asexually propagated by cuttings in 2007and the resulting plants were subsequently found to be true to typedemonstrating that the characteristics of the new variety are stable andtransmitted without change through succeeding generations. Since theinitial propagation in vitro propagation has also been carried outsuccessfully.

SUMMARY OF THE INVENTION

‘ZZ04120’ is characterised by a semi-upright bush habit and attractive,medium blue, large fruit with good flavour which harvests around mid-tomid-late season. ‘ZZ04120’ is distinguished from a number of othervarieties and by its parents by the following characteristics:

The bush habit of ‘ZZ04120’ is semi-upright while ‘Duke’ is upright, andflowering starts a week earlier than ‘Duke’. The fruit of ‘ZZ04120’ islarger than that of ‘Duke’.

‘ZZ04120’ has lighter skin colour than its parent ‘Brigitta’ and flowersand fruits earlier than ‘Brigitta’.

‘ZZ04120’ has larger fruit than its paternal parent B7-8-1.

DETAILED DESCRIPTION

The observations, unless otherwise specified, were made in the2015-2016, 2016-17 seasons on 5-6 year old plants grown at, Motueka, NewZealand. All dimensions in millimetres, weights in grams (unlessotherwise stated). Colour terminology is in accordance with The RoyalHorticultural Society Colour Charts (R.H.S.C.C.) fifth edition.

-   Plant and foliage: This plant is generally spreading to upright in    growth habit. The surface texture of one year old canes are smooth    while the surface texture of mature canes (of three year old wood)    is slightly rough and peeling; the colour of immature canes is near    yellow-green 153C. The colour of the bark of mature canes is near    brown N200C. The mature leaf is lanceolate in shape with an acute    shaped leaf tip and typically averages 59 mm in length and    approximately 30 mm in width. The margins are generally entire, and    the leaf has slight glossiness on the upper surface. Pubescence is    absent from the leaf upper and lower surface. The upper surface of    the leaf is near yellow-green 147A and the lower surface near green    138B in colour. The petiole typically averages 3 mm in length.-   Inflorescence: The typical flower has an average flower length of    11.2 mm and the diameter of the corolla aperture averages 4.5 mm.    The average diameter of the corolla tube is 7.7 mm. The average    style length is approximately 9.5 mm. The main colour of the petals    on fully open mature flowers is near white N155B. The pedicel length    averages 6.1 mm, with peduncle average length 14.5 mm.-   Fruit: The fruit are of large size, averaging approximately 2.6 g    (observed range 1.1-3.2 g) and clustered with an average of 14    berries/cluster. Fruiting occurs on one year old shoots only;    flowers do not occur on current season's shoots. The time of    beginning of fruit ripening on one year old shoots is mid-season    (early-mid December), similar to that on ‘Duke’. Generally fruit is    oblate with an average diameter of approximately 17 mm (observed    range 15-19 mm). Ripe fruit generally has a skin colour of near    violet-blue 98D with bloom intact and near black 202A with bloom    removed. The bloom is moderately strong. Internal flesh colour of    ripe fruit is near greyed-yellow 160C. The calyx aperture is round    on a ripe berry and has an average diameter of 6 mm. The depth of    the calyx basin is shallow. The attitude of the incurving sepals    tends to be horizontal. The pedicel scar is small and generally dry.    The fruit is firm and the fruit sweetness (Brix level) averaged    12.1. Yield is high, averaging approximately 7 Kg per plant. The    self-compatibility of the new variety has not been tested by    self-crossing the variety. However, it is recommended to associate    the plant with other varieties with similar flowering timing to    maximise pollination and fruit set.-   Events: Vegetative bud burst occurred about the third week of    September under New Zealand growing conditions. Time of beginning    flowering mid-late September, similar to ‘Duke’ or ‘Elliott’.    Maturity period: mid-late season; fruit ripened on trial plants at    Motueka, New Zealand in a similar season to ‘Duke’, 50% of the crop    was ripe around the 22 December.-   Pest and disease: The plant does not seem to be susceptible to rust    (Pucciniastrum vaccinii). No symptoms of anthracnose or    Botryosphaeria have been observed under New Zealand growing    conditions.-   Additional description: The variety has been observed to be suited    to production of blueberries for fresh consumption. The plant cold    hardiness according to the American zone classification has not been    determined. However, the chilling requirement of ‘ZZ04120’ has been    estimated to be 1000+ hours.
